Kuznetsov NK-33 Engine Comeback - The Russian Engine Built for the Moon Is Back!

The legendary NK-33 rocket engine is back in the spotlight as Russia’s United Engine Corporation showcases a full-scale model on Cosmonautics Day. Originally designed for the Soviet Union’s ambitious N-1 Moon rocket, the NK-33 remains one of the most advanced rocket engines ever built—even decades after its creation. In this video, we explore the incredible history of the NK-33, developed under chief designer Nikolai Kuznetsov, and how it was meant to power Soviet cosmonauts to the Moon. Despite the failure of the N-1 rocket program, the NK-33 survived—and later stunned the world with its performance when rediscovered in the 1990s. We also break down how its revolutionary oxygen-rich staged combustion cycle influenced modern rocket engineering, including technologies seen in SpaceX engines. From Cold War secrecy to modern lunar ambitions, the NK-33 continues to shape the future of space exploration. Could this decades-old engine hold the key to future Moon missions? And why are engineers still studying its design today?
